This invention relates to locking devices and has particular reference to locks4 oi jiininyproof character.

'Among the objects of this invention is to provide a lock having astrilie which is attached to the jeinb in e novel manner, being' reen'orced to prevent the saine from being so separated troni the jzunb, by wedge shaped tools or the likethat are commonly employed lo pry oil the strike of a jimmyproot loci; or similar device.,- zis to limit the inward swing ot thedoor should the strike be pried loose.

Another object of this invention isV to provide a loci( having a movable ineinber which is preferably in the forni oit a chain or the like and adapted 'for use in connection with the lock casing to limit the degree to which the door may be opened, but said .chain being likewise adapted as en enehorage for the strike to limit the opening of the door when the strike is pried from the jemb.

Another object of this invention is. to provide a loci: having a movable member such as a chain, and a. compound bolt which is adapted for closing the lock and preferablyy in a jinnny-proof manner, said holt being also adept'ed to engage said movable member, seid movable member being connected to'the jamb whereby o forcible entry as by prying the strike from the jainb is rendered impossible, said movable member being also engageable with said casing in such manner as to slightly opened. e f

Another object oi' this invention is to provide e lock havingy a movable ,member such as e chainfvvhieh is connected to the jainb and is engagea-ble either ivith the bolt of the lock or directly with1 the lock casing depending upon 'Whether itis desired to retain the door in closed lor slightly open position.. I

Another object of this invention is to pro- `"vide slots in the easing so as to allow for the ndjnstnient of the loch `lo correspond with the strike irrespective of the tendency of the parts to become ont of nlinen'ientj due to sagging, warping, shrinking, or the like.,

it beingr understood that the usual nionner in which'e, "burglar attacks a jinnny-prooi" loch is by inserting a chisel or the like hetween the door andA jamb and forcing' the chisel beneath the ienge of the strike with permit the door to be' the result that the screws holding 'this tiange to the jalnb are loosened; it becomes then a relatively easy matter to open the door by exerting suilieient pressure inward theres. on to detach the 'remaining screws which secure the strike to the tace or the jainh. This invention seeks to prevent that condition by means set forth more particularly hereinbefore. he invention includes generally a holding means which can be secured' to the jainb remotely from the edge thereof and in spaced vertical relation to the lock casing whereby a plurality of holding members can be used, said holdingn members being adapted :tor use both when the door is closed and when it is open, being available. in all cases to hold the door slightly ajar.

Still another object of thisinvention is to provide novel anchor plete for holding the barrel of the loch in place and whereby a material savingin time and labor is efeoted when the lock is being' mounted upon the doorh Yiith the foregoing and other objects in vieny the invention consists in the arrange- ,nient and combination or" parte hereinafter described and. claimed, and While the invention is not restricted to the exact details@ of constructiondisclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the saine parts in the several views, and in which- Figure 1 is e horizontal section ott a por tion of the lock, the lock being shown mounted and in locked position.

.Figa 2 is a similar View in' elevation. Fig'. is en edge view of the strike. i Fig. e'lis a vieiv in elevation showing the lock mounted in operative position, parts of the lock beinglg` in section to show e step in opening the lock. Y

Fig; 5 is a view in elevation showing a typical use of the lock 4with the door slightly ojar,

Referring' now more specifically to the drawings, I shon7 my lock as comprisin a casing` l0 mounted upon a door il, an( ay strike 12 upon a jamh 13. liovable means is mounted upon the iznnb so arranged as to i be adapted to strengthen the locked condition as between the door and the g'zimb, said movable means being for this purpose conceived oi as a device which is engageable with the strike to 'reenforce the lsienne in its attachmentto the liambLor as a device which is engageable directly with means borne by the door such as the bolt of the lock, but. preferably in such manner as to engage said bolt through the strike whereby the strike is reenforced and direct engagement. with the bolt secured. Said movable means is shown in the form of a flexible device such as the chains 14 which are secured to the jamb in any suitable manner or position but preferably by anchor members 15 spaced somewhat from the edge ot the iamb and in spaced verti -al relation to the strike as 'for instance above and below the same. The chains, any desirable number of which may be used, have connection With aA central keeper or link 16 which is suitable for the urpose. The vertical pull upon'the chains 1s balanced and a reenforccment of uniform character produced.

The master link or keeper 16 is enga eable with means at the strike or upon tue lock casinU. Thus the strike is provided with an opening 17 through which the link is insertable into the strike in position to be engaged by a bolt having a compound motion or otherwise suitably arranged for the purpose. More specifically said bolt comprises an outer rigid member or shell. 18 Within which a locking member 19 is movable, for engagement with the link by means of a tongue 20. Preferably a plurality o said locking members are provided to engage said link simultaneously from both sides thereof. Suitable means are provided for causing said locking members to engage the link when the bolt is projected and to release the same when the bolt is partially retracted in relation to the casino. Thus I provide automatic means such as the springs 21 which are operative to cause the locking,r members to move out of engagement with the master link. The locking members 19 are aranged for oscillation as by being mounted upon pins 2Q secured in the shell 18 and which support also the springs. The locking members are 'for this purpose grooved at 23 as shown in Fig. 1 thus providing ay pair of lugs 24 on each member between which a spring is positioned. The springs bear between the inner end ot the shell 1S of the bolt and the shoulder portions of the locking members at said grooves so as to throw said members to the sides of the shell or away from each other. As means for actuating the locking members toward the central axis ot the lock for engagement with the master link, the lugs 24 are made ot' extended size to engage a portion 25 of the end wall of the lock casing adjacent to the striking.,r edge of the door, to canse a tilting of said locking members when said lugs strike the same as the bolt is projccted. The member 9.5 is thus seen as dividing the openv ing in the lock casinzgl into a plurality of smaller openinrfs similar to those seen in the strike in Fig. The shell i3 thus s en to be of approxinmiel).y U-iorm. 'l'be sides of tbc U arc preferably flanged at the ends`r atthe sides, and also at the crotch of the U shown at 26, 27, and 9.8, respcctivcly, thus forming a sort; of box construction, within which the locking members 1i) are positioned at. the sides of the U, the pins Q2 engaging opposite flanges 1T on each side of the shell. When they bolt is slightly retracted into the casing' as shown in Fig'. -l the lugs 2l more out ot abutment relation with the member 25 and the springs l lill, the locking members to tinv sides ot' the shell till they strike the sides ot the U. The strike is provided with means for properly support.- ing the master link in position to be engaged by the locking members. 'llius l provide an opening 29 opposite tp the opening t7, the link being; supported in both of sani openings. Due to the. form of the shell 18 the master link is readily inscrtahle into the openings 1i' and 2S) whether the bolt projected paritally into the strike or letrai'ted therefrom, and thence the operator desiringr to leave the building and yet cause the lock to assume the condition as in Fig. 2, may insert the keeper into the strike before he passes out, and when the bolt is projected into the strike it will interlock with the keeper asshown. Should the .strike be lorcibly detached from the jnmb by burglars, the chains as in Fig. 1 would hold the strike and prevent. the door from being opened,

` As long,l as the bolt remains in projected position the master link can not be disengaged from the bolt. To preventthe dctachment ot th'c strike trom the lock casing means, as vfor instance by witlnlrnwing: the bolt vfrom the strike and dragging the link along: with il'. abutment means is provided in the strike to limit relative movement ot' the parts movable in the strike. Said abutment means takes the form preferably of a member il() extendingr across tlf-e trout .rall of the strike and diriding the openingY iberoin into a pair of openings. 'lbe member Citi lies in the path of thc master .link and pie vents withdrawal ot the bolt and lari-,per in terlockcd therewith-trom the .strike toward the casing except in the normal manner by unlocking the locking' members' lll. 'l`be lock is jimmy-proof also in the broad aspect of a bolt haring locking: members' ll) thel tongues 20 ot which arc movable to engagior interlock lbehind or ahnt against the mvmbcr 30 though l pret'er to arrange my invention as set forth lwreinbct'ori` with llulink interlock. ll'hcn the, door is 'iimmicd the bolt maintains ils projcctwl relation to the casing` and hence'tbc lugs Eiland abntment :'25 keep the locking membcrs projected behind the abutment in position lo impingc against it, thus limiting the degree lll) lill
